A side wall and door of the Saigon Opera House have also been smeared with scribbles, affecting the aesthetic of the building that is now 123 years old.
Work on the theater began in 1898 and was completed two years later. It has a facade facing Dong Khoi Street in District 1, and is one of the typical European architectures leftover from the French period.
L’Opera de Saigon was designed by French architects in the Flamboyant style, a phase of late Gothic architecture from 15th-century France and Spain.
HCMC announced in September that the building will be restored at a cost of VND337 billion (US$13.86 million).
